type PlainText = Integer Source

type CipherText = Integer Source

data PubKey Source

Constructors

PubKey
Fields bits :: Int e.g., 2048 nModulo :: Integer n = pq generator :: Integer generator = n+1 nSquare :: Integer n^2

Instances

data PrvKey Source

Constructors

PrvKey
Fields lambda :: Integer lambda(n) = lcm(p-1, q-1) x :: Integer

Instances

genKey :: Int -> IO (PubKey, PrvKey)Source

_encrypt :: PubKey -> PlainText -> Integer -> CipherText Source

deterministic version of encryption

generateR :: SystemRNG -> PubKey -> Integer -> Integer Source

encrypt :: PubKey -> PlainText -> IO CipherText Source

decrypt :: PrvKey -> PubKey -> CipherText -> PlainText Source

cipherMul :: PubKey -> CipherText -> CipherText -> CipherText Source

ciphetext muliplication is known as homomorphic addition of plaintexts

cipherExp :: PubKey -> CipherText -> PlainText -> CipherText Source

Homomorphic multiplication of plaintexts An encrypted plaintext raised to the power of another plaintext will decrypt to the product of the two plaintexts.
